MTL 8913-PS-AC – AC Mains Power Supply Module | MTL8000 Series Platform
Engineering Background
The MTL 8913-PS-AC is a dedicated AC mains power supply module engineered for the MTL8000 series of Zener barriers and galvanic isolators, manufactured by MTL Instruments (now part of Eaton’s MTL product line). This module delivers stable, regulated DC bus power to the MTL8000 backplane, enabling safe and reliable signal conditioning in hazardous-area installations across oil & gas, chemical processing, and power generation facilities worldwide.
Product Positioning
As the primary power source for MTL8000 DIN-rail-mounted safety barrier systems, the 8913-PS-AC eliminates the need for external DC power supplies. Its wide-range AC input (85–264 V AC) ensures universal compatibility with global mains voltages. The compact plug-in form factor enables rapid field replacement without disturbing adjacent barrier modules — a critical advantage in live process environments where uptime is non-negotiable. Procurement engineers specifying MTL8000 system power infrastructure will find the 8913-PS-AC the definitive solution for AC-powered installations.

- Redundancy Ready: Supports dual power supply configurations on the MTL8000 backplane for N+1 redundancy in critical SIS applications.
- Compact DIN-Rail Footprint: Integrates directly into the MTL8000 system without additional panel space or external wiring.
- Decades of Field Reliability: MTL8000 platform has an extensive installed base in IEC 60079 hazardous-area applications worldwide.
- ATEX / IECEx Certified: Fully compliant for use as associated apparatus in Zone 1 and Zone 2 classified installations.
MTL 8913-PS-AC System Architecture & Signal Flow
The MTL 8913-PS-AC mounts into the dedicated power supply slot of the MTL8000 backplane. AC mains is connected to the module’s screw terminals; the module converts and regulates this to the DC bus voltage distributed across the backplane to all installed barrier and isolator modules. In a redundant configuration, a second 8913-PS-AC (or the DC variant 8913-PS-DC) occupies the secondary power slot, with automatic load sharing and failover. The backplane’s internal bus architecture ensures that a single power supply failure does not interrupt signal conditioning to field instruments.

Technical FAQ – MTL 8913-PS-AC
Q: Can the 8913-PS-AC be used with the MTL8500 or MTL4000 series?
A: No. The 8913-PS-AC is designed exclusively for the MTL8000 backplane. For MTL8500 or MTL4000 systems, different power supply modules are required — contact us for the correct part number.
Q: Is redundant power supply supported?
A: Yes. The MTL8000 backplane supports dual power supply modules. A second 8913-PS-AC or the DC equivalent (8913-PS-DC) can be installed for N+1 redundancy.
Q: What is the maximum number of barrier modules the 8913-PS-AC can power?
A: This depends on the specific barrier modules installed and their individual power consumption. Refer to the MTL8000 system power budget calculation in the MTL8000 System Manual (INM8000).
Q: Does this module carry SIL certification?
A: The MTL8000 system is designed for use in IEC 61511 safety instrumented systems. SIL capability data (PFD, λD, λS) for the power supply module is available in the MTL8000 SIL data sheet — request from our technical team.
Q: What is the lead time for out-of-stock units?
A: Standard lead time for factory-fresh units is 4–8 weeks. Konmask.com maintains buffer stock for common MTL8000 components — contact us to confirm current availability.
